Why haven't I received my Wunderlist Pro refund?

As we're no longer charging for Wunderlist Pro as of April 4, 2018, you will be issued an automatic refund. We will begin issuing refunds to your original payment method on April 4, 2018. Please know that it may take up to four weeks for your refund to be processed back to your original payment method. Your refund will be issued automatically from the app store where you purchased your Pro subscription. You can find details regarding the Apple iTunes refund policy here and Google Play’s refund policy here.
